Description

Technical Field

[0001] This utility model belongs to the field of electronic component fixing technology, specifically a trapezoidal aluminum shell resistor fixing mechanism. Background Technology

[0002] In the installation of power equipment and electronic components, trapezoidal aluminum-cased resistors are important electronic components, and their fixing method has a significant impact on the stability and reliability of the overall equipment. Currently, most trapezoidal aluminum-cased resistor fixing mechanisms on the market adopt bolt fastening or snap-fit ​​designs. Although these structures can achieve basic fixing functions, they still have certain limitations in practical applications. Bolt fastening requires additional tools, increasing the time and cost of installation and maintenance; while snap-fit ​​designs may loosen due to long-term use or vibration, thus affecting the resistor's working performance.

[0003] Furthermore, existing mounting mechanisms often require the replacement of specialized parts or structural adjustments when adapting to trapezoidal aluminum-cased resistors of different sizes. This not only increases material costs but also reduces installation efficiency. Additionally, in certain special applications, such as high-temperature or high-humidity environments, the durability and stability of existing mounting mechanisms may be affected, thereby reducing the overall reliability of the equipment.

[0004] Therefore, we have made improvements to address the above problems and proposed a trapezoidal aluminum shell resistor fixing mechanism to optimize its ease of installation, applicability, and stability. Utility Model Content

[0005] The purpose of this invention is to solve the problems of complex installation, poor adaptability, and insufficient stability in special environments of existing trapezoidal aluminum shell resistor fixing mechanisms.

[0006] To achieve the aforementioned objectives and address the aforementioned problems, this utility model provides a trapezoidal aluminum-shell resistor fixing mechanism, comprising a clamping assembly and an adjusting assembly. The clamping assembly directly contacts and fixes the trapezoidal aluminum-shell resistor, and its internal elastic support accommodates resistor shells of different sizes. The adjusting assembly is connected to both sides of the clamping assembly, and its displacement controls the tension of the clamping assembly, thereby achieving stable fixing of the trapezoidal aluminum-shell resistor. The bottom of the adjusting assembly has a positioning element that engages with the mounting surface of external equipment.

[0007] The clamping assembly includes two opposing clamping plates. Each clamping plate has several arc-shaped protrusions on its inner surface. The surface of the arc-shaped protrusions is covered with an anti-slip layer to increase the friction between the plate and the trapezoidal aluminum resistor shell. The two clamping plates are connected by a spring. The two ends of the spring are fixed to the outer sides of the two clamping plates respectively, and the initial length of the spring is less than the maximum opening distance of the clamping plates.

[0008] As a preferred technical solution of this application, the adjustment assembly includes two screws and an adjustment block. One end of each screw is threaded to the end of the adjustment block. A through hole is provided in the middle of the adjustment block, and the inner wall of the through hole is provided with internal threads. A rotating handle is also provided at the end of each screw. The rotating handle is fixedly connected to the end of the screw. The screw is rotated by rotating the handle, thereby changing the distance between the clamps.

[0009] As a preferred technical solution of this application, the positioning component includes two symmetrically arranged limiting plates, and the outer side of the limiting plates is provided with reinforcing ribs. The reinforcing ribs are integrally formed with the limiting plates to improve the structural strength of the positioning component.

[0010] As a preferred technical solution of this application, the number of arc-shaped protrusions on the inner surface of the clamping plate is three. The three arc-shaped protrusions are evenly distributed on the inner surface of the clamping plate, and the height of each arc-shaped protrusion gradually decreases from the center of the clamping plate to both sides. The anti-slip layer is made of high-temperature resistant rubber material with a thickness of 1-2 mm, which can effectively prevent the trapezoidal aluminum shell resistor from sliding during the fixing process.

[0011] As a preferred technical solution of this application, the central axis of the spring coincides with the central symmetry line of the clamping plate, and the elastic coefficient of the spring is in the range of 50-100N / m, ensuring that sufficient clamping force can be provided during the clamping process without damaging the outer shell of the trapezoidal aluminum shell resistor due to excessive pressure.

[0012] As a preferred technical solution of this application, the inner wall of the through hole of the adjusting block is provided with a lubricating coating, which is made of polytetrafluoroethylene material, to reduce the friction between the adjusting block and the external equipment mounting column and improve the convenience of installation and disassembly.

[0013] As a preferred technical solution of this application, the outer surface of the rotary handle is provided with anti-slip texture, which makes it easier for the operator to apply greater torque when adjusting manually.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In the scheme of this application:

[0016] The clamping and adjusting components enable rapid fixing and release of trapezoidal aluminum-cased resistors. The arc-shaped protrusions and anti-slip layer in the clamping components effectively increase the contact area and friction with the resistor casing, preventing loosening due to vibration or external force. The adjusting component, through the cooperation of a screw and adjusting block, precisely controls the distance between the clamping plates, thus accommodating trapezoidal aluminum-cased resistors of different sizes without requiring replacement of special accessories or structural adjustments, significantly improving installation efficiency and applicability. Furthermore, the positioning component design allows the fixing mechanism to be securely installed on external equipment, maintaining good stability even in high-temperature or high-humidity environments, solving the problem of insufficient durability and reliability of existing fixing mechanisms in special application scenarios.

[0023] This utility model provides a trapezoidal aluminum shell resistor fixing mechanism, the overall structure of which is as follows: Figure 1 As shown, the device includes a clamping assembly, an adjusting assembly, and a positioning component. The clamping assembly consists of two opposing clamping plates 1. The inner surface of each clamping plate 1 has three arc-shaped protrusions 2, and the surface of each protrusion 2 is covered with an anti-slip layer 3 made of high-temperature resistant rubber material with a thickness of 1-2 mm. The clamping plates 1 are connected by springs 4, with both ends of the springs 4 fixed to the outer sides of the clamping plates 1. The central axis of the springs 4 coincides with the central symmetry line of the clamping plates 1, and the elastic coefficient ranges from 50-100 N / m. The bottom of each clamping plate 1 has a sliding groove 9 for use with the adjusting assembly.

[0024] The adjusting assembly includes two screws 5 and an adjusting block 6. One end of each screw 5 is threaded to the end of the adjusting block 6. A through hole is formed in the center of the adjusting block 6, and the inner wall of the through hole is coated with a lubricating coating made of polytetrafluoroethylene (PTFE). A rotating handle 7 is provided at the end of each screw, and the rotating handle 7 is fixedly connected to the end of each screw 5. The outer surface of the rotating handle 7 has anti-slip textures.

[0025] The positioning component includes two symmetrically arranged limiting plates 8, and the outer side of the limiting plates 8 is provided with reinforcing ribs 10, which are integrally formed with the limiting plates 8.

[0026] In actual operation, the trapezoidal aluminum-cased resistor is first placed between two clamping plates 1. The arc-shaped protrusion 2 of the clamping plate 1 contacts the resistor's outer casing, and the height of the arc-shaped protrusion 2 gradually decreases from the center of the clamping plate 1 to both sides to ensure maximum contact area. At this time, the spring 4 is in a compressed state, providing initial clamping force. Next, rotating the handle 7 drives the screw 5 to rotate. The thread of the screw 5 engages with the thread of the adjusting block 6, causing the clamping plates 1 to move along the slide groove, thereby adjusting the distance between the clamping plates 1. When the distance between the clamping plates 1 reaches the appropriate position, rotating the handle 7 is stopped, completing the fixing of the trapezoidal aluminum-cased resistor.

[0027] The presence of a lubricating coating reduces the friction of the adjusting block 6. The positioning plate 8 of the positioning component mates with the mounting surface of the external equipment through mounting holes, and the reinforcing ribs 10 of the positioning plate 8 improve the structural strength, ensuring that the fixing mechanism can maintain stability in high temperature or high humidity environments.

[0028] exist Figure 2 The details show the partial structure of the clamping assembly. The arc-shaped protrusions 2 on the inner surface of the clamping plate 1 are evenly distributed, the anti-slip layer 3 covers the surface of the arc-shaped protrusions 2, and the arrangement of the springs 4 is clearly visible. Figure 3 The focus is on demonstrating the assembly relationship of the adjustment components, showing the threaded connection between the screw 5 and the adjustment block 6, as well as the anti-slip texture of the rotating handle 7. Figure 4 The structure of the positioning component is shown, and the design features of the limiting plate 8 and the reinforcing rib 10 are clearly visible.

[0029] Through the above structural design, the fixing mechanism enables rapid fixing and release of trapezoidal aluminum-cased resistors. The arc-shaped protrusion 2 and anti-slip layer 3 of the clamping plate 1 increase the contact area with the resistor casing, preventing loosening due to vibration or external force. The adjustment assembly precisely controls the distance between the clamping plates 1 through the cooperation of the screw 5 and the adjusting block 6, accommodating trapezoidal aluminum-cased resistors of different sizes. The design of the positioning component allows the fixing mechanism to be firmly installed on external equipment, solving the problem of insufficient durability and reliability of existing fixing mechanisms in special application scenarios.

[0030] To enable those skilled in the art to fully understand and implement this utility model, the following supplementary explanation of the implementation principle of this utility model is provided in conjunction with specific application scenarios.

[0031] In practical applications, the trapezoidal aluminum-cased resistor is first placed between the two clamping plates 1 of the clamping assembly. The arc-shaped protrusions 2 on the inner surface of the clamping plates 1 contact the resistor's outer casing. Since the height of the arc-shaped protrusions 2 gradually decreases from the center of the clamping plates 1 to both sides, the contact area is maximized. Simultaneously, an anti-slip layer 3, made of high-temperature resistant rubber material with a thickness of 1-2 mm, covers the surface of the arc-shaped protrusions 2, further increasing friction. At this point, the spring 4 is compressed, providing initial clamping force, thus initially fixing the trapezoidal aluminum-cased resistor.

[0032] Next, by manually rotating the rotary handle 7 in the adjustment assembly, the screw 5 is driven to rotate. The threaded engagement between the screw 5 and the adjusting block 6 causes the screw 5 to move along the thread direction, thereby pushing the clamping plate 1 along the sliding groove at its bottom. As the distance between the clamping plates 1 gradually decreases, the contact pressure between the arc-shaped protrusion 2 and the trapezoidal aluminum resistor shell increases until a suitable clamping state is achieved. During this process, the elastic coefficient of the spring 4 is in the range of 50-100 N / m, ensuring that the clamping force is moderate, which can guarantee the fixing effect without damaging the resistor shell due to excessive pressure.

[0033] The through hole in the center of the adjusting block 6 mates with the mounting post of the external equipment. The inner wall of the through hole is coated with a lubricating layer made of polytetrafluoroethylene (PTFE), which reduces the friction between the adjusting block 6 and the mounting post, making installation and disassembly easier. Meanwhile, the limiting plate 8 in the positioning component mates with the mounting surface of the external equipment through a mounting hole. The reinforcing rib 10 on the outer side of the limiting plate 8 is integrally formed with the limiting plate 8, improving structural strength and ensuring stability even in high-temperature or high-humidity environments.

[0034] Once the fixing mechanism is installed, the trapezoidal aluminum-cased resistor is securely clamped between the clamping plates 1. The arc-shaped protrusions 2 and the anti-slip layer 3 on the inner surface of the clamping plates 1 work together to increase the contact area and friction, effectively preventing loosening due to vibration or external force. Furthermore, the adjustment assembly, through the cooperation of the screw 5 and the adjusting block 6, can precisely control the distance between the clamping plates 1, accommodating trapezoidal aluminum-cased resistors of different sizes, without requiring replacement of special parts or structural adjustments, significantly improving installation efficiency.

[0035] In actual operation, to release the trapezoidal aluminum-cased resistor, simply rotate the handle 7 in the opposite direction, causing the screw 5 to move in the opposite direction. This increases the distance between the clamps 1, and the spring 4 returns to its initial state, allowing the resistor to be easily removed. The entire process requires no additional tools and is simple and quick to operate.

[0036] Through the above steps, the fixing mechanism achieves rapid fixing and release of the trapezoidal aluminum shell resistor, solving the problems of complex installation, poor adaptability, and insufficient stability in special environments in existing technologies. The design of the clamping and adjusting components improves the fixing effect, while the design of the positioning components ensures the reliability of the fixing mechanism in various environments.
